there are no formal educational requirements for some animal training positions beyond a basic high school education, some employers may require that candidates possess some postsecondary animal education. Some schools offer programs specifically geared toward training specific animals, such as dogs or exotic species. For students who want to pursue additional education or a position that requires a bachelor's degree, universities offer 4-year degrees in animal science, zoology, or veterinary sciences that can help them start their careers. Students majoring in these programs may take such classes as animal nutrition, mammalian anatomy and physiology, animal communication, and aquatic ecosystems.
